Well, you don't make up straw men that makes you inferior. Paul never met Jesus, James did and also was the leader of the (clearly) very important Jerusalem church. Paul knew and admitted that he lacked authority, hence he had to sell his ideas very hard to the readers of his letters. Nothing suggest that he intended for those letters to outlive him (the vast majority probably didn't) or become the backbone of a new religion. It just so happened.

The Pharisees in the gospels are good examples of straw men, though.
